Can someone help me find this manwha please?

So basically..It’s BL, and I can’t remember but of it. But I’m pretty sure the bottom was like an investigator or something? Probably not that’s just what I think. And the dom is a celebrity. I know that the dom was in this like art program, and the ‘manager’ or leader whatever of this art program was like really creepy, and he was obsessed with the dom or something and he stored a painting the dom did in a ‘special’ room or something. And he like,, abused his students or something?? And he dom left the art program but the creepy guy wants him back. I think the bottom had black hair and he was nonchalant, and the dom had like blonde hair. Please helpp!! I really wanna read this story again!!

(And also if someone can tell me the title of the manwha in my pfp that would be great too..ples)
